The Rise and Fall of R&D Networks

Date 12 Apr 2013
AbstractDrawing on a large database of publicly announced R&D alliances, we track the evolution of R&D networks in a large number of economic sectors over a long time period (1986-2009). Our main goal is to evaluate temporal and sectoral robustness of the main statistical properties of empirical R&D networks. By studying a large set of indicators, we provide a more complete description of these networks with respect to the existing literature. We find that most network properties are invariant across pooled and sectoral networks. This result suggests the presence of universal laws governing the dynamics of R&D networks. Moreover, we find that many properties of R&D networks are characterized by a non-monotonic trend with a peak in the mid-nineties. This allows us to define the mid-nineties as a "Golden Age" characterized by the rise-and-fall of R&D networks. Finally, we show that many properties of empirical R&D networks support predictions of the recent theoretical literature on R&D network formation.
